The invention discloses an aquatic feed based on
selenium yeast and application thereof, and belongs to the technical field of
aquaculture. The invention relates to an aquatic
feed additive based on
selenium yeast, which systematically studies the influence of addition of different
selenium sources (organic selenium and
inorganic selenium) into feed on the growth performance,
muscle nutrition, texture characteristics, serum
biochemistry and main
nutrient components of muscles of
hybrid culter. The cultivation efficiency of the
hybrid culter can be obviously optimized by enhancing the feed organic selenium, and the specific expression is as follows: the growth rate increase and the feed conversion efficiency improvement have obvious
dose dependence; the selenium deposition amount and the crude
protein enrichment degree in
muscle tissue are synchronously improved, meanwhile, the synergistic effect of
essential amino acid composition optimization (EAA / TAA value improvement) and n-3 series
fatty acid characteristic enrichment is presented, and the two-way improvement of the
nutritional quality and the
flavor value is achieved from the molecular nutriology level. Mechanism research shows that the intervention strategy verifies the comprehensive regulation and
control effect of the intervention strategy on the body health status by remarkably reducing the activity of
serum transaminase (AST and ALT) and the
total cholesterol concentration, effectively promoting the steady-state reconstruction of
liver metabolism and activating an endogenous
antioxidant defense
system.
